Patented June 28, 1932 PATENT OFFICE WILLIAM L. BRYDEN, OF CLEVELAND,OHIO I ADJUSTABLE RECLINING CHAIR Application filed November 14, 1929iSerial'No. 407,070.

' My invention relates to adjustable reclining chairs, and moreespecially to this type of chairs having a supporting web of canvas orother suitable flexible materlal unsupported between the ends of theweb, but affording adesirable support for invalids in particular, bothin an erect or reclining position.- It is also desirably collapsible.

It is a special feature 1 that a pivoted relation between an horizontalparallelogram at the usual position of the arms,eand anotherparallelogram extending downward from the forward ends of the horizontalbars of the first, retains the foot rest in a substantially horizontalposition, when the chair is adjusted toany position of which it iscapable, and a very pleasing control of the chair is thus afforded bythe pres- 7 sure of the feet on the foot rest by the 00011: ant.

While the pivoted frame of the chair is shown in the drawings in fulllines as supported by cross bars intended to rest on the floor, it is myintention to provide means for suspending the frame from an overheadsupport, as shown in dotted lines. Either means for support may be used.

My invention consists in certain novel features which will behereinafter fully described, then more particularly pointed out in theappended claims, and is illustrated in the accompanying drawings inwhich- Figure 1 is a perspective view of the chair,

Figure 2 is a central longitudinal section of the reclining chair inerect position;

Figures 3 and 10 are side elevations of the chair shown in its recliningand collapsible positions, respectively;

Figures 4, 5, 6 and 7 are vertical sections shown in the planesindicated by the numerals 44, 5-5, 6-6 and 7-7, respectively; and

Figures 8 and 9 are horizontal sections taken in the planes indicated bythe lines 88 and 99, respectively. I

Fig. 11 is a side elevation of the chair.

Fig. 12 is a perspective view of the chair, shown in a verticallysuspended position.

As shown in full lines, the adjustable back of my construction hereshown in a substantially erect position;

ends of the outer bars 16 are further conof the chair compriseslaterally spaced vertically inclined bars 5 having their upper endsconnected by a transverse rod 6. The lat-. ter affords means forsupporting the upper end of the canvas web 7 which may be readily foldedabout the rod in a loop for attachinent. At points 8 intermediate theends of these bars 5, I have pivoted forwardly extending horizontal armbars 9 upon the forward ends of whichare pivoted the downwardlyextending bars 10 by the cross pins 11, and the bars 5 and 10 arefurther'connected by horizontal bars 12 whose forward ends are pivotedto the cross pins 13 which are intermediate the ends of the bars 1-0,the bars 66 12 being pivoted at a point somewhat spaced from theirrearends, as at 14, to the lower ends of the bars 5, at said points bysuit able pins. ,7

The above construction will thus be shown to positively retain bars 5and 10 in parallelism, by reason of the positioning of the bars 9 and 12in parallelism, this being a desired relation of these very importantparts.

7. If the chair is intended torest upon a plat 7 5 form or floor of anykind, I will support it upon a pair of X-standards comprising bars 15and 16, the upper ends of eachof thesebars 15 and 16 being pivoted tothe corresponding pivoted bars 5 and 10,respectively', of the 30corresponding side of the chair frame. The pivotal connections of thestandards to the 7 bars 5 and 10will' be at the points-17 and 18,

respectively, intermediatethe points 8 and 14 of-one, andth'e pivots 11and 18 ofthe'other. 35

Each pair of the standards thus pivoted, comprises the bars15 and 16which are detachably braced'against each other by blocks 19 securelyfastened on the face of each bar, as by nails or screws, the block oneither bar pressing downward against the upper edge of the other bar, asshown clearly in Fig. 1 of the drawings. The bars of each standard mayreadily collapse by swinging on their pivots, when the chair is to befolded up as shown in Fig. 10. a

The swinging frame will itself serve as a cross bracefor the twostandards. The lower n'ected-by a rod 22having pins enteringthe' tillbars 16 and secured to them in the manner shown in Fig. 8. The blockfixture is shown well in Fig. 6.

A foot rest comprises a flat board 23 whose ends are securely attachedto parallel levers 24. The latter are'pivoted at their rear ends 26 andintermediate their ends at 25, to the lower ends of bars 27 and 10,respectively, so that the latter bars are maintained in parallelism, andthe upper ends of bars 27 are pivoted at points 28 on the bars 12, sothat the bars 24 remain parallel to the bars 9 and 12, just as the bars5, 10 and 27 are always parallel. The foot board 23 is mounted upon aforwardly extended end of the levers 24, and therefore may be adjustedvertically, but is always maintained in a nearly horizontal plane.

Since the lower bars 12 are positioned somewhat inwardly from thevertical plane in which the bars 9 are located, and the standards 15 and16 remain spaced quite outside of the plane of the pivoted bars, I haveprovided spacer bars 29 extending from the pivot 11 to the pivot 18'andpositioned between the upper end of the bars 10 and the forwar ends ofthe bars 9 and 16, as is well shown in Figs. 1 and 4. For a similarreason, I have provided rings 30 upon the pivots 8 between the bars 5and 9, as shown in Figs. 1 and 5.

The X-standards are nowhere connected with the main frame of the chair,except at the pivots 17 and 18, and these pivots remain spaced at asubstantially constant distance apart. It has been found advantageous toextend the rear ends 31 of the bars 12 beyond the pivots 14, wherebythis extension 31 may serve as a means for preventing the top of thechair from falling below a desired limit, as will be evident from theview in Fig. 3 of the drawings. While I have shown the foot board 23mounted upon an inclined edge 32 of the bars 24, it need not be inclinedto the length of such bars, nor inclined at any particular angle tothem.

- In some cases it may be desirable to suspend the chair from anoverhead support of some kind, and I have shown in. Fig. 12, cables 33so suspended, and have illustrated eye fixtures 34 which are located atthe pivots l7 and 18, and may serve the common purpose as such pivotpins and the means for attaching the cables 33. Neither means of supportneed be retained. while the other is being used.

It will be seen from the drawings and the foregoing description that mychair comprises a pair of laterally spaced articulated frame members,each of which comprise the substantially horizontally extending bars 9,12 and 24, which are pivotally connected to the vertically inclined bars10, 27 and 5, thereby forming two parallelograms, one of which is formedby the horizontal bars 9 and 12 and the-vertically inclined bars 10 and5 the other of which is formed by the vertically inclined bars 10 and 27and the horizontal bars 12 and 24. These transverse frame members arejoined together by suitable transverse rods 6,-

and 13 and the foot rest 23, thereby forming an articulated structurewhich supports the canvas web 7 heretofore described.

Whatl claim as my invention and desire to secure by Letters Patent is- Apivotally adjustable and collapsible reclining chair comprising incombination, a stationary supporting frame including a pair of spacedX-frames, a swinging frame pivote-d upon the upperends of said X-frameand comprising laterally spaced members connected by transverse rods,and a flexible memher having its ends suspended from the said rods, thesaid X-frames comprising cross bars each provided with a supportingblock detachably resting upon the upper edge of the other bar, and theswinging frame including in each of said spaced members three paralleland spaced horizontal bars pivotally connected with parallel verticallyinclined bars,

whereby the swinging frame may swing back-- ward to nearly horizontalposition, and it together with the X-frames may be swung forward tocollapsed position.

In witness whereof, I have hereunto set my hand this 8th day ofNovember, 1929.

WILLIAM L. BRYDEN.
